Remarks

Touch events do not use the same event model as other Windows Phone input events such as MouseLeftButtonDown. Rather than being exposed as an element-specific event that potentially routes through the object tree of a UI, the touch input event is a single event handled at the level of the application. You then use the TouchFrameEventArgs and call GetPrimaryTouchPoint versus specific UI elements and their bounds. This determines the specific touch point frame of reference within your application's UI layout.

Touch input requires hardware that is touch-sensitive, as well as an environment that supports the infrastructure needed to expose touch events to individual applications.

Version Notes

Windows Phone

This uses an entirely different touch input model. For more information on touch input, manipulations and gestures for Windows Phone, see How to handle manipulation events for Windows Phone 8.
